Description

Combustor design for materials i.e. the melting glass charge

The present invention relates to burner, be specifically related to multi-jet burner structure.

The batch melting that successive glass melting method needs to pile up usually becomes melten glass liquid stream admixtion to remain in the formula smelting furnace of a kind of pond, and heat supplied is until this material is fused into a pond fused glass metal stream.Usually comprised a large amount of melten glass in the melting pool,, thereby reached certain degree of uniformity so that before discharge glass forms operation, have enough residence time to rest on the liquid-flow state of melten glass.These recycle streams in the molten kiln of pond formula may cause utilizing heat energy fully.Traditional overhead radiation heating is inadequate, because the admixtion that this radiating capacity has only the part directive to be melted.

Surrogate as the traditional tank formula glass furnace of narrating above, the US Patent No 4381934 of Kunkle and Matesa discloses a kind of method of strengthening admixtion liquefaction, and admixtiones a large amount of in this method can be liquefied in quite little liquefaction vessel.This method only produces quite a spot of high-temp waste gas, is particularly using the time marquis who strengthens thermal source.Heat in the waste gas also can be recovered and be used to the cooperation materials flow that direct heating enters liquefaction vessel, thereby improves one's methods total thermo-efficiency.

When the heating admixtion makes its liquefaction, thereby realize on the admixtion that the most handy burner exposes that maximum flame covering effectively utilizes heat in stove.When disposing burner, the some factors that will consider are arranged in order as disclosed in US Patent No 4381934, to heat the cooperation bed of material in heating container effectively.When the flame of burner too when cooperating the bed of material, the impact of flame may make the bed of material become unstable.Thereby the bed of material may collapse in container down, causes that bed thickness is irregular, forms undesirable product.In addition, the eddy current that produces therefrom may cause discharging the Dust Capacity of taking away in the air-flow at burner increases.Another factor that will consider is that flame should be directly facing to the upper area that cooperates the bed of material, because high heat may produce deleterious effect near refractory materials.In addition, if must move after one section long distance could heated wall for burner flame, just then thermo-efficiency has lost.

To cooperate the bed of material in order more effectively heating, can to dispose other burner, make in heating container along cooperating the bed of material to have better flame distribution.Flame covers though this has produced preferably, a kind of so alternative method, owing to need extra burner hardware and corresponding instrument, maintenance and cooling conditions, thus make heating means complicated.

As a kind of alternative mode, can use and have multi-jet single burner reducing the number of burner, and keep effective flame distribution simultaneously.Single burner just can be diffused into burner flame and cooperate on the bed of material and do not increase extra instrument or upkeep cost.Many shower nozzles burner can be configured in the bed of material near, its nozzle can be configured to make burner flame to act in the mode of nuzzling up to cooperate on the bed of material rather than directly point to the bed of material.The many flames that obtain the thus formula burner that nuzzles up can cooperate heat distribution on the bed of material, and has reduced the eddy current that produces on the bed of material owing to the flame percussion simultaneously.

The multiple exit burner can be heated flame distribution makes the heat that is transferred on the admixtion reach maximum to the bed of material, and has reduced the direct impact of flame to admixtion and flame retardant coating on every side simultaneously, and this point is favourable.

The US Patent No 3127156 of Shephard has illustrated the burner that a kind of flame location is controlled.Many concentric tubes separate Oxygen Flow, airflow, fuel stream and water along the length of burner.There are two circular channels to be used for water by cool burner.Next door in the circular channel has guaranteed that water enters from an inlet attack, crosses the length of burner along an effluent, and the opposite side along burner forwards outlet connection to then.This burner has a single flame export on the top of burner.

The US Patent No 3515529 of Love etc. has illustrated the burner that a kind of side that is used for the thermal storage type glass smelting furnace emits.Cooling liqs is introduced in the chamber identical with burner length.The burner liquid fuel for example with the oil fuel of pressurization, need not be introduced pressurized air and make the atomizing means.This burner has only an outlet, and flame is crossed ejaculation from the side of burner.

The US Patent No 4391581 of Daman etc. has illustrated a kind of burner with the heated combustion air channel of fuel injection, and this combustion air channel couples together the parts of checker brick with the thermal storage type glass smelting furnace.A single pipe core passes through water-cooling jacket with this fuel guiding of for example Sweet natural gas, is injected to air passageways tunnel current from a unique nozzle then and cools off angled tip portion by water-cooling jacket.

An object of the present invention is to provide a kind of burner of multiple exit,, obtain better heat distribution so that the flame of burner is spread on the cooperation bed of material.The oxygen catheter of fuel conductor and contained gas is housed in the outer sleeve, and these conduits and sleeve are isometric.Supravasal opening is mixing fuel and gas in the mixing section of burner length.Nozzle on mixing section is directed to predetermined direction with the flame that produces.Be contained in the sleeve and and the cooling jacket of the equal in length of burner make the refrigerant cool burner that in sleeve, circulates.In one embodiment of the invention, the first part of burner determines the position of burner in heating container, and the second section of burner comprises burner nozzle.These two portions can be that angle deviating is arranged mutually.

Shuo Ming multi-injector burner to charge level, makes flame spread more effectively to heat than single outlet burner in the present invention.These nozzles are configured on the part of burner longitudinal extension, and the part of this extension can be stretched to any one direction.Therefore, burner can meet the charge level of its heating.For example, if charge level is crooked, then the part of Yan Shening can be parallel to this charge level substantially, and therefore a plurality of nozzles can distribute burner flame more equably.In addition, burner nozzle in the present invention can be configured to make flame to be distributed on the charge level rather than directly to point to charge level along the direction of nuzzling up, thereby reduces the percussion of flame, and keeps the stability of charge level when heating.Because fuel device of the present invention can replace several single outlet burners and have effective heat distribution, so parts and relevant maintenance are fewer, check that the requirement of burner has reduced, heating unit has also been simplified.

Another object of the present invention is the many flame oxygen/fuel burner that provides a kind of heating to use around the charge level of center furnace chamber.The elongated portion of burner extend in the furnace chamber, and the nozzle that is provided with at interval along this part is then with the burner flame guide surface.

As shown in Figure 1, in liquefaction vessel 10, still unfused admixtion stabilizing layer 34 is maintained on the wall of rotating cylinder 12, and around the center furnace chamber, burning is carried out in this hole.The flame 36 of burner 32 make the surface portion 38 of admixtion 34 become liquid and stay mobile, by the bottom opening 24 of outlet unit 20.The admixtion of liquefaction flows out liquefaction vessel 10 then, is collected in the container (not shown) below liquefaction vessel 10, so that further process on demand.Waste gas can be discharged by bottom opening 24 downwards, perhaps makes progress by the opening on the top cover 26 and enter exhaust outlet 40 to discharge.

Though in the present invention without limits, the burner 32 shown in Fig. 2,3,4 and 5 preferably has L shaped configuration, and along its shank that stretches out 44 many nozzles 42 is set.As discussed below, the shank 44 that stretches out provides the distribution of the burner flame 36 that needs.Specifically with reference to figure 2, burner 32 also comprises outer tube 46, burning gas conduit 54 and the fuel conductor 56 that has

end plate

48 and 50 round conduit 52 now, constitutes a chamber that utilizes conduit 52 to make the coolant flowing that enters burner 32.Should illustrate that burning gas cited below is meant purity oxygen and contains the oxygen of gas, also comprises and can support any other gas of incendiary together with fuel.In order to protect burner 32 not to be subjected to the infringement of the hot environment of heating container 10, refrigerant 58 enters into burner 32 by entering the mouth, and by the whole length of conduit 52, flows out from opening end 60 then, though the best water of the unqualified water of refrigerant.Refrigerant is full of outer layer sleeve 46, flows through betwixt, flows out burner 32 from exporting 62.Combustion gases and

fuel

64 and 66 enter burner 32 by entering the mouth, and utilize

conduit

54 and 56 to keep separately when circulation respectively.

End plate

68 and 70 has sealed the end of these conduits, and combustion gases and fuel are separated with the refrigerant that flows to outlet 62.With reference to figure 4 and Fig. 5, gas and fuel are mixed at nozzle 42 places at opening on the gas duct 54 72 and the opening on fuel conductor 56 74.Each root pipe 76 forms the mixing section of gas/fuel mixture and also this mixture is guided to the direction that needs at nozzle 42 places.Because burner 32 is subjected to by conduit 52 and the cooling of sleeve pipe 46 coolant circulating, all welding assembling and other joint or appurtenances all are watertight.Because high temperature and corrosive environment, the parts of burner are preferably stainless, but also can be the material of any other type, as long as this material can work long hours in the sort of environment.

In most preferred embodiment, as shown in Figure 4,

conduit

54 and 56 is orthogonal, and common wallboard 78 is arranged, but should be understood that, also can use the conduit of other configuration.For example, for the people who is familiar with this technology clearly, rectangular pipe and other similar configuration that a pair of its tangent plane wall is placed by wall will be equal structures.Though opening 72 and 74 shown in Figure 5 is orthogonal, this opening can be Any shape and size, for example, circle, oval and end is the rectangle of curve etc., as long as this shape and size can provide gas/fuel mixture and the flame characteristics that needs.In addition, the opening 72 and 74 at any one nozzle place differs to establish a capital and wants same size and configuration, again it, this opening also can change with nozzle one by one.

Should be understood that the fuel, gas and the refrigerant configuration that in explanation of the present invention, have comprised other.For example, Fig. 6 shows a kind of rectangle sleeve pipe 146, and this sleeve ring is around burning gas conduit 154 and fuel conductor 156, and conduit 154 and 156 square section generally are circular.Opening 172 and 174 in gas duct 154 and fuel conductor 156 makes gas and fuel mix at 176 places in the mixing region respectively.Dividing plate 80 separates sleeve pipe 146 and the entry 82 of refrigerant and the escape passage 84 of refrigerant is provided, and refrigerant flows through these paths and cooled off burner 32.

As shown in Figure 4, the spread angle A of pipe 76 flame 36 that will determine burner 32 in conjunction with the size and the configuration of opening 72 and 74.Pipe 76 can be changed into for example circular cone tangent plane, thereby further changes spread angle.Though in the present invention without limits, spread angle is preferably between about 10 to 15 °.This spread angle has been concentrated the flame 36 of burner and this flame has been directed on the cooperation bed of material better, thereby makes on the charge level 38 of the more close admixtion 34 of whole flame, more effectively heats admixtion.

Burner configuration as shown in Figure 1 understands for example how the coverage area of flame is directed, and makes on flame 36 and admixtion 34 surface portion 38 that is diffused into admixtion 34 in an acute angle.Because the angle between burner flame and the charge level part 38 is successively decreased since 90 °, thus flame pass through along charge level, rather than directly with charge level percussion mutually.So because more charge level is arranged is directly to be exposed to this configuration of stability flame 36 and don't that influence admixtion 34 can be effectively give admixtion with the heat transmission and make its liquefaction.

Fig. 7 is similar to the square section that Fig. 4 shows a kind of burner 32, also shows second nozzle 86 except that nozzle 42.Nozzle 42 and 86 each other approximately meets at right angles, but also can become the burner configuration of angle to obtain wishing that is fit to of any requirement.Sleeve pipe 46 has also been sealed

conduit

52,54 and 56 except beyond the extra fuel conductor 88.Lead at the additional opening 92 on opening on the fuel conductor 88 90 and the gas duct 56 on the pipeline section 94 of nozzle 86.Clearly, as an alternative, conduit 54 and 88 can be made the combustion gases conduit, and conduit 56 can be used as fuel conductor.Nozzle can by shown in the left-hand part of Fig. 8 in couples the configuration in groups, perhaps interconnected by carrying out shown in 8 the right hand portion.This multi-nozzle configuration can be used in the burner configuration of any hope.

With reference to figure 9, another fuel conductor or gas duct can be joined on the burner 32, so that around burner, provide extra nozzle location.Specifically, coolant duct 52 passes a pair of gas duct 54 and a pair of fuel conductor 56.At opening on the gas duct 72 and the opening on fuel conductor 74 gas and fuel are mixed at nozzle 42 places.

Also can be used for other by Fig. 2 to burner internal structure shown in Figure 5, this is as by Figure 10 and those burner configurations shown in Figure 11, but is not limited to these configurations.Except make as shown in Figure 2 nozzle 42 along shank divide 44 one-tenth horizontally beyond, if desired, also can make nozzle 42 ground that is perpendicular to one another spaced apart, to accord with the surface that admixtion 34 exposes substantially.If heating operation allows, nozzle 42 can also be adjusted, and it is sprayed directly on to flame 36 cooperates on the charge level.As a kind of replacement, specifically with reference to Figure 11, nozzle 42 also can become non-perpendicular direction with flame 36 guiding charge levels at the longitudinal axis with burner 32.In addition, can increase the spacing of nozzle 86 or change spout to reach the variation of the burner configuration that needs.

Again with reference to Figure 11, stability at the bed of material is in the melting appartus of significant consideration, and the flame size of burner 32 each spouts can be changed, and just must have only the top of the direct percussion of less flame at the material wall, bigger flame then nuzzles up along its underpart, has therefore kept the stability of material wall.

Should be understood that other burner configuration that adopts burner of the present invention and designs of nozzles is also applicable to any heating or melting operation.Because nozzle 42 is localized along the cardinal principle longitudinal extension part of burner 32, for example the shank shown in Fig. 2 44 reaches fully and the configuration that effectively heats so the extension can be any requirement.For example in the method for fusion of discussing in front, in container 10, can use a kind of annular burner completely so that a kind of successive curtain formula flame charge level that nuzzles up to be provided.Be that burner 32 can have many extensions as shown in figure 12.I.e. public beam barrel 98 outwardly directed 96 parts from the end of master unit 100, an available single center gas and the more zone of fuel source heating.In addition, 96 parts can be protruding to form the multi-nozzle multistage burner at different level attitudes from the beam barrel 98.

Here narration and illustrational form of the present invention are represented in the explanation of illustrative most preferred embodiment.Certainly carry out various changes under the situation determined of the present invention will putting in following claim.
